Bovine coronavirus (cattle)

First of all, it must be clarified that bovine coronavirus is a different disease from human coronaviruses. To date, there is no evidence that COVID-19 has been found in cattle or that bovine coronavirus can be transmitted to humans.

Bovine coronavirus manifests three different syndromes: neonatal diarrheal syndrome of the calf, dysentery and respiratory infections.

Bovine coronavirus (cattle)

The most common symptoms of neonatal diarrhea syndrome are profuse liquid diarrhea, sometimes with hemorrhage, anorexia, dehydration, and ultimately death. Dysentery initially affects adult calves and can cause severe diarrhea and decreased milk production.

This virus is commonly transmitted in calves when mothers have diarrhea that is not treated or in cases where they do not inherit immunity when given colostrum and therefore do not acquire the antibodies necessary to generate immunity. This virus is more stable in cold climates, so it is more common to appear during the winter.

Bovine coronaviruses can also cause mild respiratory disease or pneumonia in calves up to six months of age. The virus is eliminated into the environment through nasal secretions and feces, and contact with these causes contagion.
